In the days leading up to the G7 summit in Quebec, Donald Trump spent a lot of time on Twitter trashing Justin Trudeau. At the gathering, he showed up late to scheduled events and declined to cooperate. Then, as he left early to spend time with a murderous dictator, he refused to sign the customary joint agreement that closes out these occasions. Oh, and he described the Canadian prime minister as “weak and dishonest,” while one of his top trade advisers said Trudeau should burn in hell. All of this, of course, was precipitated by the U.S. imposing steel and aluminum tariffs on Canada, Mexico, and the E.U., yet Trump thinks Trudeau has treated him unfairly because his country levies a minuscule tax on dairy. One would think the thrill that went down Trump’s leg when he shook hands with new beau Kim Jong Un would be enough to get over “backstabbing” Trudeau and le traîtreEmmanuel Macron. Days later, however, despite having other very big things on his plate, Trump is still fuming.

Yes, speaking to reporters in Singapore following his summit with gulag enthusiast Kim, Trump continued to lash out at our mild-mannered neighbor to the north and promised to mete out more financial punishments for allies that dare match his provocations.

“When I got out to the plane,” Trump said. “I think that Justin probably didn’t know that Air Force One has about 20 televisions. And I see the television and he’s giving a news conference about how he will not be pushed around by the United States and I say push him around? We just shook hands. It was very friendly . . . No, I have a good relationship with Justin Trudeau. I really did, other than he had a news conference, that he had because he assumed I was in an airplane and I wasn’t watching. He learned. That’s going to cost a lot of money for the people of Canada. He learned. You can’t do that. You can’t do that. We have a big trade deficit with Canada . . . It’s either $17 [billion] but could actually be $100 billion. You know they put out a document, I don’t know if you saw it. They didn’t want me to see it, but we found it. Perhaps they were trying to show the power they have. It’s close to [a] $100 billion-a-year loss with Canada. They don’t take our farm products—many of them.”

It’s not clear exactly which portion of Trudeau’s characteristically mild-mannered response to the G7 summit Trump perceived as a slight. The Canadian prime minister merely reiterated what he’s said since the U.S. announced it would hit Canada (and the rest of America’s allies) with steel and aluminum tariffs on “national security” grounds, despite, as Trudeau has pointed out, Canada always having America’s back. “It’s kind of insulting,” he told a reporter, as Trump watched from Air Force One. “I have made it very clear to the president that it is not something we relish doing, but it is something that we absolutely will do, because Canadians, we’re polite, we’re reasonable, but we also will not be pushed around.”

Kim, meanwhile, runs a slave state made up of a network of prison gulags and presides over an “all-encompassing indoctrination machine.” A 2014 United Nations report accused North Korea of “extermination, murder, enslavement, torture, imprisonment, rape, forced abortions and other sexual violence, persecution on political, religious, racial, and gender grounds, the forcible transfer of populations, the enforced disappearance of persons, and the inhumane act of knowingly causing prolonged starvation.”

But Trudeau said he wouldn’t acquiesce to Trump’s tariffs without a reciprocal response, and Kim shook Trump’s hand and smiled and gave him the big P.R. win he was looking for. “His country does love him,” Trump said of Kim in an interview Tuesday morning. “His people, you see the fervor. They have a great fervor.” Maybe he meant fever?
